Done — `index.html` contains the full animated synthwave scene: - **Sun**: gradient disc (gold → hot pink) with horizontal scanline gaps that widen toward the bottom, clipped at the horizon so it "sets," plus a soft radial glow and a slow bobbing motion - **Grid**: perspective neon grid with converging cyan→pink lines and exponentially-spaced horizontal rows scrolling toward the viewer, glowing brighter as they approach - **Stars**: twinkling multicolored starfield above the horizon, plus occasional shooting stars - **Reflection**: mirrored sun glow on the ground with shimmering animated stripes - **Extras**: sky gradient, horizon glow line, vignette, and a pulsing neon "SYNTHWAVE" title Everything runs in one self-contained file with no external resources. Just open `index.html` in a browser.

EVALUATION

4/5 working

Static synthwave sun, scanlines, grid, and stars render nicely but show no visible grid scroll or input response.

MEASUREMENTS

Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
